To all whom. if may concern:

Be it known that we, HJALMAR TAnvr'rILfi. and Jenn Soncini, citizens, respectively, of the United States and Finland, and residents, respectively, of Chicago, in the county ot @ook and State of illinois, and Crosby, in the county ot Crowv l/Ving and State ot Minnesota, have jointly invented certain new and useful Improvements in Railway Switches, of which the following is a speciiication.

yThis invention relates to improvements in railway switches and its object is to provide a switch which may be thrown by manually operated means to run the train upon a sid ing and then, by the same means, thrown to` permit a train to travel over the switch upon the main line in a direction away from the siding and immediately thereafter the train upon the siding may pass out upon the main line without the switch being opened by hand, and said train may again pass over the switch past the siding.

With the foregoing and other objects in view the invention consists in the combination and arrangement of parts to be hereinafter fully described, pointed out in the appended claims and illustrated in the accom panying drawings which form a part of this application and in which- Fig. 1 is a plan view with the switch Fig. 2 is a similar view with the switch open.

Fig. 3Kis a section taken on line 3-3 of Fig. l.

Fig. 4 is a section taken on line 4 4 oi' Fig. 1. i

Fig. 5 is a section taken upon line 5-5 of Fig. 1.

Fig. 6 is a perspective view ot the guide other or to keep the casing extended. The

end of the bolt/6 remote trom the rail 3 `is supported in an angle iron 10 which is se cured to a pitman 11 that is supported in guide brackets 12, 12 secured to and depend- 'from `the stock rails, and saidpitmen is iormed with or carries a lug 13 adapted tor engagement with the guide-rail 5; the pitman 11 is connected by the link 14 with the foot 15 of the manually lever 16.

17 denotes a bolt secured to the stock rail 1 and extending through the guide rail 5 and casing 18 and supported by the standard 1 9 secured to a rail tie 20. `The casing 18 is open at one end and in the open end ia nut 2O"1 is disposed upon the bolt 17 and a spring 21 within said casing yabuts the closed end of the same and the nut and tends to force the casing away from the said nut, together with the guide rail 5. A. bolt 22 secured to the switch rail 4 extends through the guide rail 5 and into a casing 23 and said bolt is supported by a standard 24 secured to a rail `tie 20; in the open end of the casing 23 a nut 26 is disposed upon the bolt and a spring 27 abuts the same and the closed end of the casing and tends to move said casingand guide rail toward the switch rail 1.

Referring to Figure 4 of the drawings it will be apparent that as the member 11 is moved to the left, transversely tothe rails, the memberl 10 through the medium of the spring 9 will force the switch rail 3 against the rail 2 as shown in Fig. 1. This leaves the main line open and thus the movement of the member 11 in conjunctionfwith the spring members 7 and 26 control the move `ment oi the switch rails 3 and 4.

Operation z-In ease trains running in opposite directions upon the standard rails appreach each other at the siding, the switch may be thrown open to `permit the train approaching the siding to enter upon the same; after which it is closed by the operator or switchman. The other train now runs over the switch and continues upon its journey. Nith the switch still in closed position the train upon the siding new backs upon the main line, the flanges of the wheels forcing the switch rail and lguide rail away from the operated ,switch` i stock rails against the tension of the several y so that the train can resume its jouinej,1 without tho necessity oif manual operation of the switch.

Yillhat is claimed is The combination with the tails of the main line, one of which is intesectecl by a pivotal i'aih which oiins a Continuation of the main line iail, oi' a rod ti'ainsi/*ei*self, slidahle thoreunclei", switch rails, the one aoljalsont said pivotal main line rail being a oontinua'tion oi said main line rail, tho other being pivotally oonneotefl to the remaining switch rail, a guide "fail lying` adjacent to said lasU mentioned switchv rail and having its upper end pivoteiflL in juxtaposition With said pivotal switch i'ail, a spring buffer noiinallv holding the fi'oe end oi the pivotal rail of the main line in position to close the main line, a retraction spring connected with and normally holding the remaining switch pointv and guide rail against the main line so as to close that rail of the main line, abutinents on said rod engaging said buffer and said pivotal switch rail, and means for shifting said rod to open said main line.

In testimony that We claim the foieggoing` as oui' own We have hereto affixed oui1 signatures in the presence of subscribing Wit nesses.
